Polybenzoxazine on the horizon?
Benzoxazine veteran Dr. Hatsuro Ishida at Case Western Reserve University has developed what he calls the fourth generation of this versatile high-heat, high-strength matrix resin.

Composites for repair (2015)
Composites now offer a cost-effective means repair and/or strengthen structures made of steel, concrete or other materials.

Tooling (2015)
Composite parts are formed in molds, also known as tools. Tools can be made from virtually any material. The material type, shape and complexity depend upon the part and length of production run. Here's a short summary of the issues involved in electing and making tools.

The matrix (2015)
The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal or carbon. Here's a guide to selection.

The matrix
The matrix material binds the fiber reinforcement, gives the composite component its shape and determines the quality of its surface. A matrix can be polymeric, ceramic or metallic. Polymer matrices are the most widely used for composites in commercial and high-performance aerospace applications.
